14 The iswspace() function is the wide-character equivalent of the iss‐
15 pace(3) function. It tests whether wc is a wide character belonging to
16 the wide-character class "space".
17
18 The wide-character class "space" is disjoint from the wide-character
19 class "graph" and therefore also disjoint from its subclasses "alnum",
20 "alpha", "upper", "lower", "digit", "xdigit", "punct".
21
22 The wide-character class "space" contains the wide-character class
23 "blank".
24
25 The wide-character class "space" always contains at least the space
26 character and the control characters '\f', '\n', '\r', '\t', '\v'.
27
29 The iswspace() function returns nonzero if wc is a wide character
30 belonging to the wide-character class "space". Otherwise it returns
31 zero.

37 The behavior of iswspace() depends on the LC_CTYPE category of the cur‐
38 rent locale.
